Setup: ADC36 pin on proj brd (TXD1) to sparkfun RX, GND and 3.3 v from project board pins to respective GND, 5v Sparkfun board. Note- you must use the 3.3v version, and the PCB board stencil still shows 5 v - but YOU MUST USE 3.3V (I don't know if they have made a change for later units, this one was manf. in may of 2011....)

Port 0 is set up already to communicate via the usb connection to terra termPort 1 is set up for the defaults needed for the sparkfun PIC
